(Configuration of power management system)
FIG. 1 is a diagram showing the configuration of a power management system 1 according to the first embodiment. The power management system 1 includes a server 100, a server 200, an electric vehicle 10, and an EVSE (Electric Vehicle Supply Equipment) 20. Note that the server 100 and the EVSE 20 are examples of a "power management device" and a "power stand" of the present disclosure, respectively.

Server 100 includes a processor 101, a storage device 102, and a communication unit 103. Note that the processor 101 and the communication unit 103 are examples of a "control unit" and an "acquisition unit" of the present disclosure, respectively.

The storage device 102 stores programs executed by the processor 101 as well as information used in the programs (for example, maps, formulas, and various parameters). The communication unit 103 includes various communication I/Fs. Processor 101 controls communication unit 103 . Specifically, the processor 101 communicates with the server 200 through the communication unit 103. Further, the processor 101 communicates with a mobile terminal 15 (for example, a smartphone or a tablet) that can be carried by the user through the communication unit 103 .

The server 100 also stores information on the plurality of registered electric vehicles 10 (hereinafter also referred to as "vehicle information"), information on each registered user (hereinafter also referred to as "user information"), The EVSE 20 information (hereinafter also referred to as "EVSE information") is configured to be managed. User information, vehicle information, and EVSE information are stored in the storage device 102 while being distinguished by identification information (ID).

The user ID is identification information for identifying the user, and also functions as information (terminal ID) for identifying the mobile terminal 15 carried by the user. The server 100 is configured to store information received from the mobile terminal 15 separately for each user ID. The user information includes the communication address of the mobile terminal 15 carried by the user and the vehicle ID of the electric vehicle 10 belonging to the user.

The vehicle ID is identification information for identifying the electric vehicle 10. The vehicle ID may be a license plate or a VIN (Vehicle Identification Number). The vehicle information includes the action schedule of each electric vehicle 10.

EVSE-ID is identification information for identifying EVSE 20. The EVSE information includes the communication address of each EVSE 20 and the state of electric vehicle 10 connected to each EVSE 20. The EVSE information also includes information indicating a combination of electric vehicle 10 and EVSE 20 that are connected to each other (for example, a combination of EVSE-ID and vehicle ID).

The server 200 is a server that manages the power status of the accommodation facility 300. The accommodation facilities 300 include hotels, hot spring inns, and the like. The accommodation facility 300 is equipped with a solar power generation facility 301 that can generate electricity using sunlight. In addition, in the accommodation facility 300, the energy equipment of the entire building is integrally monitored and automatically controlled by BEMS (Building Energy Management System).

Furthermore, the accommodation facility 300 is equipped with an EVSE 20. The EVSE 20 is provided, for example, in the parking lot of the accommodation facility 300. The number of EVSEs 20 may be one or more than one.

EVSE20 means vehicle power supply equipment. Electric vehicle 10 is configured to be electrically connectable to EVSE 20. For example, by connecting the charging cable 21 connected to the EVSE 20 to an inlet (not shown) of the electric vehicle 10, it becomes possible to transfer electric power between the EVSE 20 and the electric vehicle 10.

The electric vehicle 10 can exchange electric power with the accommodation facility 300 via the EVSE 20. The electric vehicle 10 is configured to be capable of control including external power supply and external charging (hereinafter referred to as power control). Note that the electric vehicle 10 may be configured to allow only one of external power supply and external charging.

Further, the electric vehicle 10 may include a DCM (Data Communication Module), or may include a communication I/F compatible with 5G (fifth generation mobile communication system).

The server 100 acquires information regarding the power status of the accommodation facility 300. Specifically, the server 100 (communication unit 103) acquires the above information from the server 200 through communication.

Server 100 (processor 101) requests the user of electric vehicle 10 to perform power control in EVSE 20 based on information regarding the power state of accommodation facility 300 acquired by communication unit 103. Specifically, the processor 101 requests the user to perform power control in the EVSE 20 of the accommodation facility 300.

For example, when the accommodation facility 300 is low in power, the processor 101 requests the user to supply power to the accommodation facility 300 by providing external power supply. Note that the power state of the accommodation facility 300 includes not only the current power state of the accommodation facility 300 but also the expected power state of the accommodation facility 300 in consideration of the expected amount of power generation by the solar power generation equipment 301, for example.

In this case, the processor 101 transmits the above request to the user's mobile terminal 15 through the communication unit 103. Note that the above request may be transmitted to the electric vehicle 10.

Here, in the power management system 1 configured as described above, it is desired to increase the number of users of the accommodation facility 300 by promoting the use of the accommodation facility 300.

Therefore, the processor 101 grants the user a benefit regarding the accommodation facility 300 when a predetermined condition regarding power control is satisfied by the user.

Further, the users to whom the above request is sent include, for example, users who have used the accommodation facility 300 in the past. Further, the users to whom the above request is sent may include users who are located (residing) within a predetermined distance from the accommodation facility 300. Further, the processor 101 may display the above request on the screen of the above application while the user is making a reservation to use the accommodation facility 300 using an application or the like. Further, the users to whom the above request is sent may include users staying at the accommodation facility 300 and users who have completed reservations for use of the accommodation facility 300. Note that the processor 101 may transmit the above request to all users managed by the server 100.

Further, the processor 101 may select the user (electric vehicle 10) who transmits the request based on the SOC (State of Charge) of the electric vehicle 10. For example, when the accommodation facility 300 is short of power, the processor 101 may send the above request to the user of the electric vehicle 10 with a high SOC. Furthermore, if the accommodation facility 300 has a surplus of power, the processor 101 may transmit the above request to the user of the electric vehicle 10 with a low SOC.

Further, the above predetermined condition includes that the electric vehicle 10 is electrically connected to the EVSE 20. Specifically, the processor 101 provides a benefit to the user based on the fact that the electric vehicle 10 of the user who responded to the request is electrically connected to the EVSE 20 of the accommodation facility 300. Grant. That is, the user cannot receive the benefit unless he or she electrically connects the electric vehicle 10 to the EVSE 20 while complying with the above request. Further, even if the user electrically connects the electric vehicle 10 to the EVSE 20 without responding to the above request, the user cannot receive the above benefit.

Note that the privilege may be given to the user on the condition that the power control is performed for a predetermined period of time or more (for example, 15 minutes or more) (or that the user makes a setting to perform the power control for a predetermined period of time or more). Further, when the electric vehicle 10 is electrically connected to the EVSE 20, the privilege may be given to the user even if the user does not respond to the above request.

Further, if the user responds to the above request, the privilege may be granted to the user before the electric vehicle 10 is electrically connected to the EVSE 20. In this case, the granted benefit may be validated based on electrically connecting the electric vehicle 10 to the EVSE 20.

Note that a predetermined penalty may be imposed on a user who has been given a privilege and does not perform power control in the next power control in the EVSE 20 of the accommodation facility 300 or the EVSE of another facility. Specifically, even if the user performs the power control, the control may be such that a predetermined reward (the above-mentioned privilege, monetary reward, etc.) is not given to the user.

Furthermore, in the first embodiment, the processor 101 adjusts benefits depending on the user's degree of contribution in power control. In other words, the processor 101 adjusts the benefits depending on the user's contribution to the user's power control request. For example, if the user is requested to supply external power due to a power shortage in the accommodation facility 300, the processor 101 adjusts the benefit according to the amount of power supplied through power control (degree of contribution to resolving the power shortage). In this case, the benefit may be adjusted not only by the amount of power supplied but also by other factors (for example, the power supply start time and the power supply time).

Furthermore, the above benefits may be adjusted based on factors other than the degree of contribution in power control. For example, the above benefits may be adjusted based on current or past power usage in the user's accommodation facility 300 (accommodation room, room used).

Moreover, providing the above benefits includes, for example, reducing the usage fee of the accommodation facility 300. The usage fee for the accommodation facility 300 includes accommodation fees, usage fees for restaurants and facilities (gym, entertainment room, etc.) within the accommodation facility 300, and the like. Further, the usage fee may include a fee required for early check-in to the accommodation facility 300 and a fee required for late check-out from the accommodation facility 300.

Moreover, providing the above-mentioned benefit includes providing a complimentary ticket (coupon) and points that can be used at the accommodation facility 300 and the store 30. The above-mentioned complimentary coupons and points are provided through an application that can be used on the mobile terminal 15 or the like. Note that the above-mentioned complimentary ticket may be given directly to the user (hand-delivered without communication).

The store 30 shown in FIG. 1 is, for example, a store near the accommodation facility 300. The store 30 includes, for example, a store where bicycles can be rented. Users (users of the accommodation facility 300) who meet the above-mentioned predetermined conditions in the power control are given complimentary tickets or points that allow them to rent a bicycle at a lower price than usual at the store 30.

Additionally, additional (or more valuable than the above benefits) benefits may be provided to users who perform power control during the day.

Furthermore, since it is thought that the sales at the store 30 will increase due to the provision of complimentary coupons or points that can be used at the store 30 to users, even if a predetermined amount of commission (margin) is paid to the accommodation facility 300 by the store 30, good.

Moreover, providing the above-mentioned benefit includes providing a predetermined service at the accommodation facility 300 at a price lower than the normal fee corresponding to the above-mentioned predetermined service. For example, the predetermined service includes a service that provides drinks (tea, alcohol, etc.) for free.

Note that, although the example in which power is supplied from the electric vehicle 10 to the accommodation facility 300 has been described above, the present disclosure is not limited to this. If the accommodation facility 300 has a surplus of power, the user may be requested to use the power of the accommodation facility 300 to charge the electric vehicle 10 by performing external charging. In this case, the benefit may be adjusted based on the amount of external charging of the electric vehicle 10, the charging start time, the charging time, etc. (degree of contribution to eliminating power surplus).

When external charging is required as described above, the user is given a benefit corresponding to the electric vehicle 10 being connected to the EVSE 20 earlier than the normal check-in time (for example, 12 o'clock). It's okay. In this case, a benefit is given for performing external charging by the electric vehicle 10 (contribution to eliminating power surplus) during a time period when the amount of power generation by the solar power generation equipment 301 is relatively large.

Furthermore, in the case where external charging is required, this corresponds to the case where the user of the electric vehicle 10 uses the accommodation room for work etc. at a time earlier than the normal check-in time (for example, from 11:00 to 15:00). A benefit may be given.

In these cases, the benefits may include, for example, tickets for use of the gym and bath at the accommodation facility 300.

Furthermore, the user may be able to select at least one of the various benefits described above. A detailed explanation of this control will be given later.

(Power management method)
Next, with reference to the sequence diagram of FIG. 2, an example of sequence control by the power management system 1 until a privilege is given to a user will be described.

First, in step S1, the server 100 (communication department 103) receives information regarding the power state of the accommodation facility 300 from the server 200.

Next, in step S2, the processor 101 determines the user (electric vehicle 10) who requests power control. Specific examples of the selection criteria are as described above. Note that if the request is to be sent to all users managed by the server 100, step S2 may not be provided.

Next, in step S3, the processor 101 requests the user selected in step S2 to perform power control (for example, external power supply) in the EVSE 20 of the accommodation facility 300, based on the information received in step S1. . Note that the server 100 may transmit an inquiry signal for requesting power control directly to the electric vehicle 10 or to the user's mobile terminal 15.

Next, in step S4, it is assumed that the user transmits a signal to the server 100 indicating acceptance (participation in power control) in response to the power control request in step S3.

Next, in step S5, it is assumed that the electric vehicle 10 is electrically connected to the EVSE 20, thereby starting power control corresponding to the power control request in step S3.

Next, in step S6, the processor 101 calculates the user's contribution to power control. For example, the processor 101 determines the contribution level based on the content agreed between the electric vehicle 10 and the server 100 in steps S3 and S4 (charging/power feeding time, charging/power feeding amount, charging/power feeding start time). calculate. Further, the contribution degree may be calculated based on the integrated value of power control by the user (the number of times of power control so far, the integrated value of the amount of charging (power supply) so far, etc.). Note that the calculation of the degree of contribution in step S6 may be performed between step S4 and step S5. Further, the calculation of the degree of contribution in step S6 may be performed based on the actual amount of charge (power supply) after the power control is completed. In this case, the information on the amount of charge (power supply) is transmitted from the server 200 to the server 100.

Next, in step S7, the processor 101 confirms with the user whether or not to select a benefit to use. For example, the server 100 (processor 101) controls the communication unit 103 so that a message screen 15a (see FIG. 3) is displayed on the user's mobile terminal 15 to confirm whether or not to select a benefit. . A button 15b labeled "YES" and a button 15c labeled "NO" are displayed on the message screen 15a. By selecting the button 15b labeled "YES", information indicating that a selection of benefits is requested is transmitted to the server 100. By selecting the button 15c labeled "NO", information indicating that selection of benefits is not requested is transmitted to the server 100. Moreover, the process of step S7 may be performed before the process of step S6.

Next, in step S8, it is assumed that the user responds to the confirmation in step S7. That is, it is assumed that either the button 15b written as "YES" or the button 15c written as "NO" on the message screen 15a is selected.

Next, in step S9, the processor 101 determines whether there is a request for selecting a benefit from the user. If the user requests selection of a benefit in step S8 (that is, if the button 15b labeled "YES" is selected), the processor 101 determines that there is the selection request, and the process proceeds to step S91 ( Yes in S9). Further, if the user does not request selection of a benefit in step S8 (that is, if the button 15c written as "NO" is selected), the processor 101 determines that there is no selection request, and the process proceeds to step S8. Proceed to S93 (No in S9).

In step S91, the processor 101 controls the communication unit 103 so that the data on the benefit selection screen 15d (see FIG. 4) is transmitted to the user's mobile terminal 15. As a result, a selection screen 15d is displayed on the mobile terminal 15. At this time, the types (number) of benefits that can be selected on the selection screen 15d, available period, etc. are adjusted (limited) based on the degree of contribution calculated in step S6.

Next, in step S92, the user selects at least one of the multiple benefits displayed on the selection screen 15d. For example, when the button 15e (see FIG. 4) labeled "Complete" on the selection screen 15d is selected while at least one of the benefits displayed on the selection screen 15d is selected, the button 15e (see FIG. 4) selected by the user Benefit information is transmitted to the server 100.

On the other hand, in step S93, the processor 101 randomly selects at least one of the plurality of benefits prepared in advance. At this time, the processor 101 adjusts the type (number) of benefits to be selected, the usable period, etc. based on the degree of contribution. Note that the processor 101 may select a benefit by referring to the user's past usage history of benefits.

Then, in step S10, the processor 101 transmits the benefits (such as complimentary tickets and points) selected in step S92 or step S93 to the user's mobile terminal 15 through the communication unit 103.

Note that the power management method by the power management system 1 described above is an example, and the present disclosure is not limited to the above example. For example, there is no need to select benefits or adjust benefits based on contribution level.

As described above, in the first embodiment, when the predetermined conditions regarding power control are satisfied by the user and when the user uses the accommodation facility 300 (when using the accommodation facility 300), the processor 101 , a privilege is given to the user. Thereby, it is possible to increase the number of users of the electric vehicle 10 who use the accommodation facility 300 for the benefit. Further, deterioration of the power state of the accommodation facility 300 using the power of the electric vehicle 10 can be easily suppressed.

[Second embodiment]
Next, the server 110 and power management system 2 according to the second embodiment will be described with reference to FIGS. 5 and 6.

(Configuration of power management system)
FIG. 5 is a diagram showing the configuration of a power management system 2 according to the second embodiment. The power management system 2 includes a server 110, a server 210, a grid management server 400, an electric vehicle 10, an EVSE 20, and a power grid PG. The power management system 2 is a system that manages the power supply and demand state of the power system PG for each power adjustment resource (accommodation facility 300, electric vehicle 10, building 510, building 520, etc.) in the region 500. In the example shown in FIG. 5, a plurality of EVSEs 20 are provided within a region 500, which will be described later. Note that the server 110 is an example of a "power management device" of the present disclosure.

Server 110 includes a processor 111, a storage device 112, and a communication unit 113. Note that the processor 111 and the communication unit 113 are examples of the "control unit" and the "acquisition unit" of the present disclosure, respectively.

The server 210 is a server that manages the power status of the accommodation facility 300. Moreover, each of the plurality of EVSEs 20 is electrically connected to the power grid PG. Therefore, the plurality of EVSEs 20 are electrically connected to each other via the power grid of the power system PG. Although the power system PG is not shown in FIG. 1 of the first embodiment, the point that the power system PG and the EVSE 20 are electrically connected is the same as in the second embodiment.

The power system PG is a power network constructed by a power plant and power transmission and distribution equipment (not shown). In the second embodiment, an electric power company serves as both a power generation company and a power transmission and distribution company. The electric power company corresponds to a general power transmission and distribution company, and maintains and manages the electric power system PG. The electric power company corresponds to the administrator of the electric power system PG.

The grid management server 400 manages supply and demand of a power grid PG (power grid). Moreover, the grid management server 400 belongs to an electric power company. The grid management server 400 sends a request (supply and demand adjustment request) to the server 110 (communication department 113) to adjust the power demand of the power grid PG based on the power generation and consumption by each power adjustment resource in the region 500. Send. Specifically, when the power generation or power consumption of the power adjustment resource is expected to be larger than normal (or is currently larger), the grid management server 400 increases or lowers the power demand compared to normal times. The server 110 sends a request to the server 110 to do so. Note that the above demand and supply adjustment request is an example of "information regarding regional power status" and "power supply and demand adjustment request from the power system" of the present disclosure.

Processor 111 requests the user of electric vehicle 10 to perform power control in EVSE 20 based on the demand and supply adjustment request acquired by communication unit 113 . For example, when the processor 111 receives a request to increase the amount of power demand compared to normal times, the processor 111 requests the user to perform external charging in the EVSE 20. Furthermore, when the processor 111 receives a request to reduce the amount of power demand compared to normal times, the processor 111 requests the user to perform external power supply in the EVSE 20 .

Here, in the second embodiment, the processor 111 grants the user a benefit regarding the accommodation facility 300 when power control is performed in response to the supply and demand adjustment request (predetermined conditions regarding power control are met). do. Note that, in the second embodiment, the privilege is given to the user not only when power control is performed using any EVSE 20 in the area 500, but also when the EVSE 20 in the accommodation facility 300 is used.

Further, in the example shown in FIG. 5, since only the accommodation facility 300 exists in the area 500, benefits related to the accommodation facility 300 (available at the accommodation facility 300 and the store 30) are given to the user. On the other hand, if there are a plurality of accommodation facilities in the area 500, the user may be given a benefit that can be used at any of the plurality of accommodation facilities (and stores near each accommodation facility).

Furthermore, in the second embodiment, the processor 111 adjusts the benefits given to the user based on the degree of contribution to the supply and demand adjustment request from the power grid PG (grid management server 400).

Note that the peak power consumption of the accommodation facility 300 can be easily shifted (peak shift) and reduced (peak cut) by power control by the user. Based on this performance, the contract cost between the accommodation facility 300 and the electric power company is reduced, and the cost that can be spent on benefits is increased.

(Electric management method)
Next, an example of a power management method by the server 110 will be described with reference to the sequence diagram of FIG. 6. Note that the same contents as in the first embodiment will not be repeatedly explained.

First, in step S11, the communication unit 113 receives a supply and demand adjustment request from the system management server 400.

In step S13, processor 111 requests the user selected in step S2 to perform power control in EVSE 20 within area 500, based on the information received in step S11. Note that the processor 111 may request that a specific EVSE 20 (for example, the EVSE 20 of the accommodation facility 300) perform power control.

As described above, in the second embodiment, the processor 111 provides the privilege to the user when the predetermined condition regarding power control is satisfied by the user and when the user uses the accommodation facility 300. Ru. Thereby, similarly to the first embodiment, it is possible to increase the number of users of the electric vehicle 10 who use the accommodation facility 300 for the benefit.
